Title: Improving Model Estimates of Smoke Contributions to Regional Haze Using Low-Cost Sampler Systems

Project Proposal Abstract: Evaluating potential contributions of smoke dispersion, transport and deposition to regional haze from wildland and prescribed fire is difficult and costly, especially for Class I areas. Recent research indicates that various filter pack, denuder and passive monitoring systems can be adapted for remote site smoke sampling systems. We propose to adapt a combination of these systems to measure pollutants contributing to regional haze, ozone and nitrogen deposition. These systems will be robust, low-cost and useful for sampling in remote areas, making them beneficial for both local plume dispersion measures and regional haze assessments. We also propose to use these sampler systems to assess haze patterns and regional visibility models at two key regions in the Western U.S. - the Sierra Nevada, and the Grand Canyon Plateau. We will establish a network of 60 - 90 monitoring sites for a 5 - 6 month period in ech region for one year. Results from the monitoring networks will be used to describe spatial patterns of urban and smoke contributions to regional haze, and to test regional visibility models (such as CMAQ). Regional scale visibility models (such as REMSAD and CMAQ) are an alternative approach to plume disj56rsion models for measuring smoke transport and deposition. The advantage of regional scale models is that multiple fire sizes and intensities can be simultaneously included with urban air pollution in these models. Presently these models are being adapted by the Western Regional Air Partnership (WRAP) to estimate western and national regional haze patterns to support State and Tribal Air Quality Implementation Plans (SIP and TIP) in the western U.S. Making these models available for Forest Service and Interior smoke and air resource managers represents a unique opportunity to provide program support with the same modeling system used to develop the SIP's and TIP's.
